200,00 years old is about right for Homo heidelbergensis, but they need not have been in North America that long. Louis Leakey suggested about half that old for the Calico Hill site and that might be better.
These skulls are interesting because they illustrate three of Neumann's types of skulls: the one in back is the Archaic type of the Eastern Woodlands and has been compared to Iberiands and Western Europeans of the postglacial era. The skull on the left is of the Basketmaker type out of the Southwest USA and the type also goes back into the Archaic: this one has a markedly African character. The associations of the peoples in these two areas with the Iberians and North Africans is insisted on by Barry Fell: older books would have called the Basketmaker skull "Negroid" because this one is very pronouncedly African (Others are more nearly Mediterranean in type) The one very high head to the right in front is something out of one of the CroMagnon types, but it has become very short and high. In addition this individal had a form of artificial deformation apack of the head in an unusual slanting way-but this variation is also known to be the product of a specific type of artificial cranial deformation. This is a skull which is tending to be like the Adenas, and the Adenas are the ones that are most often at the base of "Giant Mound burial" stories. Female Adenas could average six feet tall or over and males at seven feet tall or over according to Robert Silverberg in the standard work The Mound Builders. antic individuals would go up from that point. Below is an Adena mound, mostsimilar to the conical mounds built in Europe by the more recent and shorter, high-headed population there. The culture that built Stonehenge also built conical mounds like this and they were remembered in Folklore as Giants.
Mordecai Rodnipoff III has provided the bulk of the material here, except for my comments on the skulls, which are an area of study I have specialised in. I do give him thanks and the credit for collecting the lippings. There are many, many more clippings like them on file.
